Rice prices must be kept within reach of the poorest people.
Let's call your number n. Twice your number is 2n. The product of your number and twice your number (so n multiplied by 2n) is 128.
Set up an equation:
n × 2n = 128
2n² = 128
Divide both sides by 2:
n² = 64
Square root both sides to isolate n:
n = 8
The question asks for half your number, so just half 8:
8 ÷ 2 = 4.
Half your number is 4.
